Specification of Letters Patent.

Appnmmn filed l mch ii, 1911. Serial in. 613,836.

To all wlwm it may coma-n.-

Be it known that I, ELLIo'rr' M; S'roRY, of Whitman, in the county ofPlymouth and State of Massachusetts, have invented certain new anduseful Improvements in Safety-Razors, of which the following is aspecification. 1

: This invention. relates to a safet' razor in which. a. substantiallyflat b ade is clamped between a blade rest formed as a runner to bearand move upon the face,,and

a guard-plate having guard fingers which coeperate withthe cutting edgeor edges of the blade in a well'known manner, a handle being providedwhich is adjustable relatively to the blade and its holder and iscapable of being locked in various positions.

The invention has for its object to provide certain improvementsrelating to means for confining the blade between the rest and guardplate, and to the means for adjusting the handle.

The invention consists in the improvements which I will now proceed todescribe same or similar parts in all the figures.

whether on one side or more, prefera In the drawings, 12 represents theblade rest which is a substantially flat plate pref-. erably ofrectangular form and preferably slightly curved backwardly at itsedgfis,

curved. ed esare hereshown but the num-- ber of sai edges may beone ormore. The outer side of the rest 12 is adapted to bear and slide on thefaoeduring the shaving operation, the blade rest therefore constltutingarunner. H j

13 represents a or (aw-threaded shank which is rigidly attached to therest 12 and p i(-io'je'cts over the central portion of its inner S] e. r

14, represents a poly" onal shouldered pro-J jeduon on the si e' of therest 12, said projection constituting the base of the Shank 13.

15 represents the blade which is a thin substantially flat plate ofsteel sharpened to form one or more cutting'edges 15. I prefer to makethe blade of rectangular form. and, to sharpen eachof its edges althoughit is obvious that one or more sharp-.

'ened edges may be provided. The proportions of the blade are such thatwhen it is in place on the rest its cutting edge or edges will projectfrom the correspondingedges of the rest, as indicated by Figs. 1 and 3.The blade is provided with a polygonal orifice 16 formed to fit and bearupon the margin of the projection 14 so that the latter prevents rotarymovement of the blade relatively to the rest 12. In case the blade hasfour cutting edges theorifice 16 engaged with the projection 14 indifferent positions, or with either pair of the cutting edges inoperative position. By pair l mean two opposite edges. v

17 represents theguard plate preferably of rectangular form andsubstantially flat.

The guard plate is formed to bear on theinner side of the blade 15, theguard plate having one or more, preferably two, of its opposite edgesserrated to form guard fingers 18 which are preferably curved, asindicated by Figs. 1 and 3, the guard fingers 'is preferably cruciformso that it may be projecting outwardly from the acting ed es s of theblade. The guard plate is provi ed with a polygonal orifice 19 whichcoincides j with the blade orifice 16 and engages the projection 14 toprevent rotary movements of the guard plate relatively to the blade restand blade. When the rest, blade and guard plate are assembled, theprojection 14 enters the orifices 16 and 19 and the shank 13 projectsoutwardly from the outer side. from the guard" plate. V V

1 20 represents a clamp which bears on the outer side of theguard plateand has a central screw-threaded socket 21 engaged with the shank 13,-so that when the clamp is rotated on the shank it acts as a nut andpresses the guard plate against -the blade and the" blade against therest. The clamp is preferably a resilient metal plate which is bent-or,curved that its. central portion containing the threaded socket 21 isofiset from the corresponding portion of the guard plate, the pressureof the clamp being therefore concentrated on portions of the guard platebetween the center and the margin of the latter, and the clamp beingadapted to more effectively confine the guard plate and blade againstmovement outwardly from the rest. The clamp is removable from the shank13 to release the blade and guard plate, and when turned inwardly on theshank to confine the blade and guard plate, its bearing portions slideon the outer surface of the guard plate in a circular path.

The clamp 20 carries a handle which as here shown includes an innermember rigidly attached to the clamp, and an outer member movablyengaged with the inner memberand adapted to be adjusted to differentpositions relatively to the latter, means being provided for locking theouter member in any position to which it may be adjusted. In theembodiment of my invention, here shown, the inner handle member is acurved bar 22 of semi-circular form attached rigidly at its ends to theclamp 20 and projecting outwardly therefrom, said bar having a concaveinner side and a convex outer side and being substantially circular incross section. The outer handle member is composed of a terminal portion23 having a transverse eye 24 which loosely surrounds the bar 22, and alongitudinal screw threaded socket 25 which communicates with said eye.The outer member also includes a grip portion 26 on vone end of which isformed a screwthreaded stem 27 engaging the threaded socket 25andadapted to bear as a set screw on theb'ar 22. A backward rotation of thegrip portion 26 and stem 27 releases the hold of said stem on the bar 22so that the outer handle member is free to move upon said bar lengthwiseof the latter and stand at the different angles indicated by full anddotted lines in Fig. 2, and is also adapted to swing crosswise of theplane of the bar 22 and assume the different angles shown by full anddotted lines in Fig. 1. When the outer member has been adjusted, it maybe locked in its adjusted position by turning the grip portion 26 to setthe outer end of the stem 27 against one side of the bar 22. thisoperation drawing the outer side of the eve 24 against the opposite sideof the bar. The outer side of. the eye and the outer end of the stemconstitute clamping jaws which are adapted to firmly grasp the bar 22and lock the outer handle member in any of the various positionsindicated in the drawings.

It will be seen from the foregoing that my invention provides a simpleand effective safety razor of relatively inexpensive construction andcomprising a relatively small number of parts, with provision foradjusting the handle at any desired angle relatively to the cutting edgeor edges of the blade. I

The bases of the guard fingers 18 are preferably oifset from the innerface of the plate 17, the latter being provided with one or moreshoulders 17 which cotiperate with the portions 15 ofvthe blade rest inspringing the blade, as indicated by Fig. 3.

I claim 1. A safety razor comprising a blade rest, a guard plate, ablade interposed between said rest and plate, a.clamp bearing on theouter side of the guard plate, means for adjustably connecting the clampwith the blade rest and causing the clamp to exert blade-clampingpressure on the rest and guard plate, an inner handle member formed as acurved bar rigidly attached at its ends to the clamp and projectingoutwardly therefrom in a plane substantially at right angles with theguard plate, said bar having a concave inner side and a convex outerside and being substantially circular in cross section, and an outerhandle member adapted both to slide lengthwise of the curved bar and toswing crosswise thereof, and provided with means for rigidly securing itto the bar in any position to which it may be moved thereon. j

2. A safety;razor comprising a blade rest provided on its back with anoutwardly projecting screw-threaded shank, a blade bearing on the backof the rest, a guard plate bearing on the outer side of the blade, theguard plate and blade beingprovided with coinciding orifices throughwhich said shank extends, a clamp bearing on the outer side of the guardplate and having a threaded socket engaging the shank, an inner handlemember formed as a curved bar rigidly attached at its end to the clampand projecting outwardly therefrom in a plane substantially at rightangles'with the guard plate, said bar having a concave inner side and aconvex outer side and being substantially circular in cross section, andan outer handle member adapted to slide lengthwise of the curved bar,and to swing crosswise thereof, and provided with means for rigidlysecuring it to the bar in any position to which it may be moved thereon.

3. A safety razor comprising a blade rest, a ard plate, a bladeinterposed between sa rest and plate, a clamp bearing on the outer sideof the guard plate, means for adjustably connecting the clamp with theblade rest and causing the clamp to exert blade-clamping pressure on therest and guard plate, an inner handle member formed as a curved barrigidly attached at 1ts ends to the clamp and projecting outwardlytherefrom in a plane substantially at right angles with the guard plate,said bar having a concave inner side and a convex outer side and beingsubstantially circular in cross section, and an outer handle memberadapted both to slide lengthwise of the curved bar and to swingcrosswise thereof, said outer handle member being composed of a terminalportion having an eye loosely surrounding said bar, one side of the eyebearing as a clamping jaw on the concave side the convex side of thebar, the stem being rotatable in the socket to cause the said jaws tograsp the bar and rigidly secure the outer handle member to the bar inany position to which said member may be moved thereon.
